摘要
In order to know whether the self-mixing laser diode can measure high speed(km/s) or not, the self-mixing laser diode maximum measurable velocity (MMV) is analyzed. Based on the three-mirror cavity model, relations of laser output power's frequency fluctuations and Doppler frequency are acquired. External optical feedback is regarded as laser's small-signal modulation by the Doppler frequency. From rate equations of the carrier density and the photon density, the conclusion of the self-mixing laser diode MMV which is restricted by laser's resonant frequency is acquired. The self-mixing laser diode MMV goes up to kilometers per second theoretically.
